Strontium decays in to radiocesium counselor? If you have discovered this, I think you may qualify for a Nobel prize.
Didn't you tell us that you were an expert on radiation and nuclear technology and that you felt in a position to lecture us on what technology is safe and which is not. You feel qualified to lecture us on what is and is not a peer reviewed article?
Once again you must resort to guilt by association (meaning that you have not bothered to open the website I provided earlier on "logical fallacies") by evoking Cheney and Bush. I will submit the following argument: Cheney and Bush are demonizing the nuclear industry by appealing, with the help of abysmally ignorant people who don't understand radiation on even the most primitive level, to the notion that that by simply saying the word "Uranium" you can justify going into other people's countries and kill them in huge numbers, tens upon tens of thousands. They could not do this without the help of scientifically illiterate people who prattle on loudly about subjects on which they know nothing. If, on the other hand, we had a scientifically literate population, such an absurdity as used by Bush-Cheney about the "Niger Uranium" purchases would be impossible. I for instance knew it was complete bullshit on the first day I saw it.
Now Counselor, I have asked you to explain the differences in chemistry between Strontium-90 and Radium-226 and their biological properties, and the relative quantities of each. I am going to go out on a limb here and come to the conclusion that you don't have a clue about this matter. So I will answer my own question.
Radium-226 behaves almost EXACTLY like Strontium-90 in biological systems. This means, counselor, that Radium is deposited in Skulls and Bones (since I know that your other obsessions involve this morphological structures and that baby teeth or just one of your ossifying interests.)
Now I will provide one of thousands of links on the Internet that include this statement or statements like it:
"Every square mile of surface soil, to a depth of 6 inches, contains approximately 1 gram of radium, which releases radon in small amounts to the atmosphere (Weast1980). The ambient outdoor radon level goes through a daily cycle of concentrations ranging from 0.03 to 3.50 pCi radon-222/L (1.11 to 130 Bq/m3)of air with the average level in the United States being about 0.3 pCi radon-222/L (11.1 Bq/m3) of outdoor air (Martin and Mills 1973).The amount of naturally occurring radon released to the atmosphere is increased in areas with uranium and thorium ore deposits and granite formations, which have a high concentration of natural uranium."
http://www.atsdr.cdc.gov/toxprofiles/tp145-c4.pdfThe energy of decay for Radium-226 is 4.871 MeV (where Mev stands for million electron volts.) Moreover, Radium 226 decays to Radon 222 which has a decay energy of 5.590 Mev. Radon-222 in turn decays rapidly to Polonium-218 of 6.118 Mev. Polonium-218 decays even more rapidly than Radon to give Lead-214 with an output of 6.115 Mev. Lead-214 decays rapidly to Bismuth 214 rapidly with a decay energy of 1.024 MeV. Bismuth-214 decays rapidly to give Polonium-214 with a decay energy of 3.272 MeV. Polonium-214 rapid decays with an astonishing 7.833 MeV to lead-210 to give lead-210, a radioactive isotope that has a half-life of over 22 years, so we'll stop here, ignoring the energy output of Bismuth-210 and Polonium-210 as they decay to the stable lead-206. - I'll cut you a break. Let's sum (this involves the mathematical operation called addition) the total decay energy resulting from one atom of Radium-226 deposited in a skull or (other) bone - noting that every human being on the planet that has ever lived since the first member of the homo genus first walked the earth has had some Radium in their Skulls, bones or baby teeth.
Here we go: 4.871+5.590+6.118+6.115+1.024+3.272+7.833 = 34.823 MeV per atom of Radium 226, ignoring Bismuth-210 and Polonium-210 decays.
Here is the decay energies of Strontium-90 and the other radioactive isotope in its decay chain, Yttrium-90 before this chain terminates in stable (non-radioactive) Zirconium-90: 0.546 Mev (Sr-90) and 2.282 MeV for a grand total of 2.828 MeV.
The difference (this involves a mathematical operation known as subtraction) is 34.823-2.828 = 31.955 MeV less for Strontium-90 than for Radium 226.
Now lets get to the punch line. There is ONE AND ONLY ONE method of preventing the formation of this horrible horrible horrible horrible problem of Radium-226 deposition in Skulls and Bones and Baby Teeth: Destroy the source of Radium-226: Uranium-238 (via energetic decays to Radium-226 through Thorium-234, Protactinium-234, Uranium-234, and Thorium-230)! How do you destroy Uranium-238?
There is ONE AND ONLY ONE way: Fission it after converting it to Plutonium-239.
If you fission Plutonium-239 with thermal neutrons, you will get, 2% of the time an atom of that awful awful awful awful awful skull and bones and baby teeth concentrating Sr-90, and 98% of the time you will not get Sr-90.
http://sutekh.nd.rl.ac.uk/CoN/nuc/S/Sr90.shtmlThis means that for every atom of Sr-90 you make, you will prevent the occurrence of 98 atoms of Radium-226 that could be deposited in skulls and bones and baby teeth! And for every atom of Radium-226 you will prevent you will prevent the occurrence of (let's count 'em; counting is the mathematical operation of generating integers by adding one to another integer starting with one) 12 other radioactive and very energetic isotopes. In fact, the quantity of Strontium-90 on the planet right now, as I pointed out in my earlier post, is dwarfed, absolutely dwarfed, by the concentration of its chemical cogener, Radium-226.
Now I will address anyone who reads this post who may actually know some science:
I think that of all the objections raised to the use of nuclear energy, there is one that is seldom mentioned, in fact never mentioned: After about a thousand years of use of nuclear energy, the total radioactivity of the earth will begin to fall rather precipitously. As life has evolved in the presence of radioactivity, there may be very poorly understood negative consequences of this state of affairs. The idea is worthy of some consideration. On the other hand, we might well argue that if we do not immediately begin to expand our nuclear capacity, the continued existence of life on this planet (owing to the Greenhouse effect) might be in more jeopardy than it would be if we stayed at the current level of total radioactivity.
